Ants could be the next line of defense against cancer.
A study published in the journal Proceedings of Royal Society B: Biological Sciences focused on Ants and their keen sense of smell. Ants use smell via their thin sensory appendages that sit on top of their heads to do almost everything, including hunt for food, spotting mates, and protecting their young.
In the study, scientists used pieces of a breast cancer tumor, which were grafted onto mice, and then trained 35 ants to associate urine from the infected mice with sugar. In analyzing, scientists detected that the ants would hover for longer periods of time near the sick mouse rather than the healthy one.
Using ants to detect cancers would be a cost-cutting tool. Currently, cancers are diagnosed by blood withdrawal, biopsies, and colonoscopies, which are all considered invasive as well as being expensive procedures. Utilizing ants to screen for cancer would be significantly more reasonable.
While dogs have similar capabilities in that they are able to detect cancer in humans through smell, they take much longer to train. Baptiste Piqueret, a postdoctoral fellow at the Max Planck Institute for Chemical Ecology in Germany, said ants would be the ideal animal to use because they have good memories, are easy to train and don't bite.
Though progress has been made with ants and their cancer detection capabilities, there is still more research to be done on their efficacy. The next phase of the study will be human trials to see if ants are able to sniff out cancers through human excrement.
Researchers report harmful levels of toxic lead were found in the bones of 46% of bald eagles sampled in 38 states. Similar rates of lead exposure were found in golden eagles, according to their study Thursday in the journal Science.
As more and more states end mask mandates and ease other COVID restrictions, discussions about the endemic phase of the pandemic have been growing. For weeks, scientists have warned about how contagious the omicron variant is, but now it seems the tone has shifted and governors are rolling back policies they've had in place for months. Dr. Eric Feigl-Ding, epidemiologist and senior fellow at the Federation of American Scientists, joined Cheddar's Opening Bell to discuss what the next phase of the pandemic might look like, how to act now that mask mandates are ending, and if we should be worried about another variant emerging.
